Background: The present study assessed calcium and pH release in newer calcium silicate based root canal sealants. Materials & Methods: The present study was conducted in the department of Endodontics. N” polyethylene tubes were cut into 30 tubes of equal sizes. Tubes were divided into 3 groups. Group I were control tubes, group II had sealapex, group III had MTA fillapex. All tubes were filled with respective materials. IN all pH and calcium ions release was assessed at 24 hours, 7 days and 28 days. Results: In group I at 24 hours, pH was 6.92, in group II was 8.23 and in group III was 8.28. Similarly, at 7 days and 28 days, the difference was significant (P< 0.05). The mean calcium ion release (ppm) at 24 hours, 7 days and 28 days shows significant difference in all groups (P< 0.05). Conclusion: Authors found that MTA fillapex showed significantly higher pH and Calcium ion release than both sealapex and control.
